Extensions and intentions in the rough set theory
593
TL;DR: The approach to rough set theory proposed in this paper is based on the mutual correspondence of the concepts of extension and intension, which makes it possible to formulate necessary and sufficient conditions for the existence of operations on rough sets, which are analogous to classical operations on sets.

New approach to covering rough sets via relations
TL;DR: New definitions to the lower and the upper approximations using a binary general relation are given using abinary general relation to represent new generalizations of Pawlak approaches.
Effects of Violent and Non-violent Computer Video Games on Explicit and Implicit Aggression
TL;DR: The results indicated both violent content and competition can arouse aggressive cognition and aggressive behavior, but only violent content canArouse aggressive behavior and cooperation has little effect on explicit and implicit aggression.

Restructuring lattice theory: an approach based on hierarchies of concepts
Rudolf Wille
- 12 May 2009
TL;DR: Restructuring lattice theory is an attempt to reinvigorate connections with the authors' general culture by interpreting the theory as concretely as possible, and in this way to promote better communication between lattice theorists and potential users of lattices theory.
